Flickering Lights May Require a New Light Switch

A Sure Sign of a Worn Out Light SwitchElectrical Question: I have a light switch that doesn’t seem to be working right, what do you think the problem might be?

I have a light fixture that can be turned On and Off by 2 different switches.

Sometimes when I flip either switch the light doesn’t come on, or the light flickers and then turns on.

One of the light switch switches seems a little loose, but the other one seems normal.

What do you think the problem might be with these blinking lights?

This question is from Amber, a Homeowner from Norfolk, Nebraska.

Replacing a Worn Out Light Switch

All of the indications in this electrical question sounds like one of your switches is getting worn out and needs replacing.

Hi Gary,
It would be best to plan to upgrade the electrical wiring throughout the home which will bring the electrical circuit wiring up to codes and make the home safer, and when installed correctly will prevent nuisance tripping breakers.

Hi Gary,
Depending on the light switch that you are referring to, yes – some worn out light switches can affect the performance of a light fixture, however the wiring of the light circuit and the electrical connections to the switch should be inspected and repaired as needed if there has been a loose connection and the wiring has become brittle or damaged.

Hi Gary – looks like you are busy with your home wiring projects – that’s Great!
The outlet that you are describing in the room where the light is flickering should be checked, paying close attention to the wiring connections to the outlet and any spliced wires inside the outlet junction box. Electrical repairs should be performed for any burnt connections and it would be best to replace the outlet if there is any signs or overheated areas where the wiring has been connected.
